To all whom t may concern:

Be it known that l, SAMUEL SHonsMrrH, a subject of the King of England, and a resident of London, in the Province of Ontario and Dominion of Canada, have invented a new and improved -Air Moistening and Cooling Device, .cf which the following is a full, clear, and exact description.

This invention relates to mechanical devices for tempering, humidifying or otherwise modifying the atmosphere of a building, such as a hospital, sick room or other place where people, either invalids or others, are in the habit of 'being domiciled.

Among the objects of the invention therefore is to provide an apparatus adapted to be located in a window Jframe or opening after either or both of the usual sashes are removed, said apparatus includingmeans.

vfor causing a spray or mist 'from a quantity of water, either in natural state or charged with sea salt, medicaments or other chemicals, patients or other people within the building or as prescribed by a physician.

More definitely stated my improvement contemplates the employment. of a frame adapted to be located inA a window opening through an outside wall of the building, said .ii-anic having journaled therein upper and the lower portion of the frame is a troughlower rollers over which an endless belt is caused by any suitable power means to roll at :i relatively high speed, the outer run of ine belt moving upwardly from a receptacle at the bottom of the frame which contains any suitable fluid to be sprayed or atomized, and said belt serving not only to convert the i'iuid into a spray or mist,'but also to carry the same over the upper roller into the buiding for the purpose of so modifying the atmosphere of the building as to render the same more agreeable or conducive to the requirements of the inhabitants or patients thereof according to the climate or other natural atmospheric conditions.

Another object of the invention is to pro-` vide improved facilities for mechanically modifying the atmosphere of a living room or hospital as to make the same conform, even in hot summer weather, to the climate at a salubrious seaside resort, and hence `by .this device Il' am able, in effect, to bring a suitable climate, so to speak, to the patient who may he unable financially or otherwise to go to a suitable climate. v

:,- With the foregoing and other objects 1n Fig. 2.

accordingto the requirements of thel view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the eXact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment'thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a vertical sectional view indicating my improved apparatus placed in a window opening in the outer wall of a building, the view being on the line 1-1 of Fig. 2 is au .inside view of the belt portion of the improvement, parts being broken awayv or omitted to show particularly the belt construction.

Referring now more particularlyto the drawings I show a wall having a window i opening of any suitable or conventional. size or form 11 and from which the window sashes are removed. 12 indicates a rectangular frame fitted intov the opening and secured therein in place of the usual sashes,

and hence substantially filling said opening 11. Said frame includes upper and lower bars 13 and 11i as well as side bars 15 and 1.6.

Secured in or otherwise supported upon like -or open topped receptacle 17 made preferably of a suitable rust-proof material of a substantial or permanent nature, and located within and .longitudinally of this receptacle is a lower roller 18 Vhaving bearings in the 'ends of the receptacle. This receptacle is adapted to contain va quantity of a suitable liquid such asy water either in its natural state or preferably charged with sea salt,

medicaments or other chemicals according to the conditions to be met or complied'with by the practice of the invention. y

In the upper end of the frame and jour- I naled. preferably in the upper ends of the sidebars and 16 is a roller 1Q having its axis parallel to the axis of the lower roller 18. Mounted upon the rollers is an endless belt 20 of any suitable flexible and preferably impervious material. The belt approxi- 'mately fills all the hole space laterally between the side bars 15 and 16 of the frame and vertically between the two rollers. The belt, therefore, in its movement around the rollers operates through the liquid in the receptacle 17. I provide, however, ai substantial space of say about six inches for an crdiequivalent, the pulley being arranged between the edge of the belt and the adjacent4 side bar of the frame. Said pulley represents a suitable transmission means for the rotation of the roller to which it is connected and hence the operation of the belt around both rollers at high speed. As a power means for operating this pulley I Vshow a rotary motor M to the shaft of which is secured one of a, series of pulleys of various sizes, the one being selected that will provide the desired rate of speed tor the manipulation ot' the belt for the best service. This pulley on the motor shaft is in dicated at 23 and a belt 24 operates over the two pulleys 22 and 23 for the purpose indicated. It will thus be seen that the belt is so operated that the outer run' thereof will move upwardly from the liquid in the receptacle and inwardly over the upper roller and thence down again to the receptacle.

The outer surface ot the belt is provided in any suitable manner with a peculiar arrangement of ribs, buckets-orA flights 20. These may be formed of the same material as the belt or any suitable material of a flexible nature so that the free movement of the belt shall not be impeded. These ribs or iights are each indicated in the form of an inverted V on the outer run or active side of the belt. In other words the apex portion of the rib moves in advance ofthe other portions upwardly through the liquid. These ribs are secured upon the central portion of the outer surface of the belt and extend laterally and downwardly from said center toward the edges of the belt., stopping, however, short of the said edges. The liquid that is picked up by these ribs as .they are moved by the belt in rapid succession upwardly through the liquid will fall or flow both directly over the ribs and laterally and downwardly toward the ends of the ribs, whereby a thorough mixture of the air takes place with the relatively minute portions or tilms of the liquid with the result that the air is charged with a maximum amount ot moisture from the receptacle. As has already been indicated the/belt isoperated at sufficiently high speed or the ribs are positioned so close together as to not only keep the liquid in a thorough state otl agitation in the receptacle but also to cause substantial portions thereof to be carried upward from the receptacle in the form of spray or mist.

25 indicates a shield inclosing the upper and outer portion ot' the trame 12 and hence shutting oil' all communication from the outhamaca side of the building direct to the vupper part of the frame. rl`he shield 25 may extend down toward the lower end of the frame to Aany desired distance, but indicated herein as extending down practically half way, but adjustably connected to the shield is a4 regulator 2G which'in effect constitutes an extension of the shield 25 lying infa [plane .parallel to the outer run of the belt. and

spaced outwardly tor may be spaced at any desired distance from the upper outer edge of the receptacle as indicated at 28 into-which space and upwardly through the channel a strong blast of iresh air is caused to circulate from outdoors. This blast of air is `torced over the upper roller 19 into the building or room at therefrom to provide av channel 27.v The lower edge of the regulathe top of the frame. Consequently the mist, l

spray or analogous means for charging the blast of fresh air with the climatizing properties above indicated will become eiiective at the space 28 and along the channel 27. 29 indicates a baffle board located within the frame adjacent to the upper end thereof and inclined downwardly and outwardly, the lower edge of the batiie board extending across between the side bars 15 and 16 and being arranged preferably directly abovev the inner'edge of the receptacle 17. 'llhis` baiiie is so located that any liquid particles carried up by the blast of humid air that tend to flyotf from the belt at a tangent as the belt turns around the upper roller 19 will be received upon the ,baiiie board whence they will flow back into the receptacle. The

major portion of the mixture, however, carried up by the blast will be disseminated throughout the building or room, any suitable outlet not shown being provided in the room at some point remote from this appa.- ratus to provide suflicient circulation of air for the purpose of the apparatus. It will thus be seen that while the liquid is carried up from the receptacle by the ribs or flights 20', the ribs being relatively small in cross section but operated at'high s eed, said liquid will be thoroughly mixe with the air entering through the space 28 and hence the air will be impregnated with the medica ments or other chemicals as may be prescribed.

I claim:
